摘要: Abstract Sm(DBM)3Phen complexes have been synthesized and studied in detail. X-ray diffraction analysis of complex reveals crystalline behavior. An enhancement the fluorescence intensity as compared to Sm(Phen)3·2H2O Sm(DBM)3·2H2O samples has observed. Stark splitting Sm3+ emission bands also The decay time for (4G5/2 → 6H9/2 transition) is seen increase from 221.6 μs 232.6 μs presence 260.6 μs Sm(DBM)3Phen. Energy transfer excited Phen DBM finally proposed cause above observations.
